CURTAIN" CONTROLLER.

Application filed November 30, 1928. Serial No. 322,744.

This invention relates to devices for retaining the lower, free ends ofcommon window curtains in adjustment.

It is desirable to maintain the lower ends of curtains, as used indwellings, ofiices and like places, at as nearly a uniform height aspossible, and because of the difference in spring tension of the curtainrolls this condition is difficult to maintain; besides which, if thecurtain is subjected to air currents, as

- when the window is open, further difficulty is encountered.

It is therefore the purpose of the present invention to produce a simplebut effective device whereby the lower end of a curtain may bemaintained in any desired adjustment in an easy and positive manner.

A further feature is in the provision of means capable of being readilyapplied to any ordinary type of curtain and readily engaged within thesash groove of any win dow at any preferred height.

Another object is to provide such devices suited to engage with windowshaving various thicknesses of sash, and, due to their simplicity, can bemade at a moderate cost.

These objects are attained by the novel construction and combination offew and simple parts, as hereinafter described and shown in the annexeddrawing, forming a material part of this disclosure, and in which Figure1 is a fragmentary view perspective of a window corner showing anapplication of the device to a curtain.

Figure 2 is a partial longitudinal sectional view of the same inoperative position.

Figure 3 is a side view of the device in detail.

Figure 1- is an edge view of the same.

In the drawing the numeral 1.0 designates in general the wall of abuilding, having a window opening provided with a frame 11 having guides12 and 13 for slidable sash, as at 14.

The curtain 15 is presumed to hang from a roll pivoted at its ends tofreely rotate at the upper end of the frame, the roll (not shown), beingof the spring actuated type to roll up the curtain when freed fromrestraint.

The bottom of the curtain 15 is hemmed and in this hem is positioned astiffening member, as the wooden barlfi, all the fore going elementsbeing old and of well known construction.

The invention consists in securing to the bar 16, preferably at one end,an eye 17 in which is secured one end of a short, light weight chain 18,the other end of which may be connected to a ring 19, movable along arod 20 of spring wire.

The rod 20 has preferably formed at one end an elongated eye 21, servingas a handle,

while the other end is offset, as at 22, and bent to form an elongatedloop 23, the long diameter of which-is somewhat greater than the widthof the guide 12.

The offset portion 22 is suited to permit the loop 23 to engage thebottom of the guideway, and its curved ends 2 1, due to the resiliencyof the wire, impinge strongly against the inner adjacent surface of theguideway when the bar portion 22 is raised, as seen in Figures 1 and 2.

The ring 19 is free to slide along the bar portion, but is preventedfrom slipping off by the eye 21 and offset element 22.

It will be apparent that this simple device may be raised and lowered asmay be desired, that it is effective, and inexpensive to produce.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

A roller curtain controller adapted to be mounted on the wooden barwithin the hem at the lower end of the curtain, and comprising a chainattached at one end to the end of said wooden bar, a spring wire rod, aring movable along said rod, to which the other end of said chain isconnected, an elongated eye formed atone end of said rod. serving as ahandle, an offset formed intermediate the ends of said rod, an elongatedopen loop formed at the offset and by the bent other end of said rod,the long diam eter of said loop somewhat greater than the width of awindow sash guide for permitting a compression of the open loop forstrongly impinging against the inner adjacent face of the guideway andallowing a ready adjustment of the curtain at any desired height:

In witness thereof I have affixed my signa u e,
